SuperSprings are adjustment free helper springs that mount above your vehicles factory springs to provide additional load support and to reduce body roll by up to 30%. This unique stabilizing system uses a shackle with a roller on each end of the springs to which allows the GMC Commercial SuperSprings to activate when needed. If needed you can level or lift from side-to-side or front-to-rear with the shackles muti-hole settings.
Trim rear shackle legs for upper bolt use.
Never load any vehicle beyond the manufactures gross vehicle weight rating (GVWR).
Mounts above factory top overloads. No additional mounting hardware required.
